REGISTERING DEVICE.

Application filed May 27, 1921.

To all whom it may concern Be it known that I, EDWARD G. THOMAS, a citizen of the United States, residing at Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Registering Devices, of which the following is a specification.

My invention relates to automatic scales. and more particularly to a scale involving 1 a registering device for the purpose of regis :tering or totaling the number of weighing operations performed. I

One object of the invention is to provide a simple device which will register the total number of articles weighed upon the scale. I Another object is to provide a counting device which will be positively operated with each weighing operation and which does not impair the operation of the scale. 7

Still another objectis to so locate the counter or totaling device that it may be easily read by the person standing before the dial. r I

Other objects and advantages will be apparent from the following description, in which reference is had to the accompanying drawings illustrating a preferred embodi .ment of my invention and wherein similar reference numerals designate similar parts throughout the several views.

In the drawings V Figure 1 is a front elevation of a scale embodying my invention, parts being broken away to show the manner of mounting the registering device;

I Figure 2 is an enlarged fragmentary view, partly in section, showing the counter and the operating mechanism therefor; and

Figure 3 is an enlarged side elevation 40 showing the counter and operating mecha- .nism in their normal positions. I

'I have shown my invention as applied to a scale of the type known as a. person weigher, with which, because of the advertising nature of such scales, it is particularly useful. It may also, however, be used for tallying the number of loads which" are passed over scales in industrial. and commercial establishments Since my invention does not reside in the Wei hin mechanism I per se, this mechanism will lie d%scribed only Serial N0. 473,100.

with such particularity as willsufiice to clearly show the connection of the other elements of the invention therewith.

As shown, the scale base 1 is con'iparatively small so that several persons cannot stand upon the scale at the same time. Secured to the base 1 and extending upwardly from the rearward end thereof is a hollow column 2. The upper end of this column is flared, as at 3, and is provided with windows 4 through which a portion of the weighing mechanism is visible. Supported upon the flared upper end of the column 2 is a substantially watch-casesha-ped housing 5 having a crystal in its forward face which displays the load-offsetting mechanism of the scale. i

The 1oad-oifsetting mechanism shown is of substantially the automatic pendulum type described and claimed in U. S. Patent No. 1,203,611, to Hapgood, November 7, 1916, and includes a pair of oppositely-swinging pendulums 6 which swing outwardly and upwardly to offset the load on the scale. The pendulum mechanism is suitably connected to an indicator hand 7 which indicates the load upon the dial displayed through the face of the housing is tached to the lower extremities of the downwardly extending ribbons 8, which are connected to the power sectors of the pendulum mechanism, is a yoke 9. The yoke is bored to receive the connecting rod 10, said rod being retained in a rigid position relatively thereto by nuts 11. Adjustment may be had by loosening one nut and tightening the I other, thus shifting the rod 10 vertically.

Snugly fitted on the lower end of the rod 10 is a bushing 12, the end of the rod being headed, as at 13, into a countersink in the lower end of the bushing, which is thereby I fixed upon the rod. The bushing is counterbored at 14 for the purpose of eliminating excess weight'and to enable the bushing to be more easily forced upon the rod. Surrounding the bushing 12 is a hollow shell-like cylinder 15, the upper end of which is externally threaded to receive a cap 16, the lower end being bored out and threaded to receive a tension rod 17, said rod being locked in position by the nut- 18.

' is a bracket 22 which carries a: counting My invention does i Resting upon a shoulder 19 of the bushing 12 andiinterposed between said bushing and the walls of the cylinder 15 is an expansive spring2O adapted to maintain thelowe'r face of the'busliingfl2' in contact withj the bottom of the cylinder.

The connecting rod 10 and tension rod 1T with the parts connecting" them thus formthe steelyard rod of'tliescale: r V
